Lophophore

The lophophore can most easily be described as a ring of ciliated tentacles surrounding the mouth, but it is often horseshoe-shaped or coiled.

The lophophore surrounds the mouth and is an upstream collecting system for suspension feeding.

they have been reassessed and placed in a new superphylum known as the Lophotrochozoa[3] in the Protostomia, which includes the Mollusca and Annelida.

[4][5] The extinct hederelloids, microconchids, cornulitids, and tentaculitids were likely lophophorates based on their biomineralization.

[6] The position of the Hyolitha has long been disputed, but as of 2017, it has been assigned to the Lophophorata as finely-preserved specimens in the Burgess Shale can be seen to carry lophophores.
